E4 has problem with stamina and ultra stamina

markour — Tue, 02 Jun 2015 21:18:36 GMT

Hello community, I have purchased a Sony Xperia E4(E2105) 2 weeks ago and I have noticed a problem with both stamina and ultra stamina modes. When I turn them on my battery drains too quickly...In stamina mode I lose 10% in 4hours and in ultra stamina 3-4% within half an hour...The first week they worked pretty fine but one day they stopped working without cause...When I check my battery usage after I have disabled stamina mode it shows that my phone was "awake" sometimes while stamina was still on but at the same time the screen was off...All the time the stamina was on I haven't used my phone at all...By the way,when my phone is in normal mode (without stamina or ultra stamina mode) it consumes only 1-2% within 10hours which shows that my battery is in very good condition....Does anyone have the same problem?I'm sorry but my english isn't that good...

You can try to reset stamina like this: first disable it, after that,go to settings-apps-all,scroll down to stamina app,force stop and clear data.Restart and see how it goes.

Can you check if the same battery discharge occurs in safe mode?

I enabled ultra stamina (while in safe mode) for about 20minutes and my battery drained 1%.In the settings I checked my battery usage info and it shows that my phone was "awake" while the same time the screen was off...

Can you try to perform a software repair?

Do you mean pc companion or factory reset?I have just finished do the settings at my phone and I do not want to do it from the beginning...Is there any possibility that Sony sends an update that will fix it?

Sorry to hear that you have issues with Stamina.

I've been testing this here but i can't find any issue with Stamina. Which build number do you have under Settings -> About phone?

Do you have an SD card in your phone and if so, do you still have this issue if you remove it?

I understand that you don't want to reset the phone when you just set it up but if possible, i would recommend that you also try the suggestion from alexdon and do a software repair.

If I get it right build number is under Kernel version?(If yes it is 24.0.A.3.8) .I have an SDcard and I will remove it in order to see if something will change and I will inform you soon...By the way I have asked a friend of mine who has the same phone to turn on stamina and check it and she has the same issue and in many forums I have seen that others face the same problem...Is there any possibility that Sony sends an update that will fix it?

Thanks for testing.

It's not a known issue and the version you have is the same one that i've been testing with here so it seems there may be an issue with your phone in this case.

Did your friend see this issue in her phone?

Yes my friend has exactly the same problem with the stamina mode...I asked her to enable stamina and watch if her battery drains as mine does...She turned stamina on and she did not use her phone for about 5 hours...The battery drained 5% in these 5hours...She checked the "battery usage" in settings and her phone appeared to be "awake" sometimes within these 5hours and at the same time the screen was off...Exactly the same thing as in mine...Also in the battery usage statistics "android system" seems to work while the stamina mode is on...It consumes a lot of battery while the phone is in stamina mode and I do not use it...Has this anything to do with my problem?

-check if any installed instant messenger (or any other) app wakes up the device. developers mostly don't optimize their app with stamina mode!!!

-beside stamina don't use greenify, that drains battery a lot.

-check what accounts try to autosync (google, facebook, sony, etc). they could try it even without any data connection!!!

-do not waste your time with pc companion repairs, that doesn't fix anything

-don't wait any miracle from stamina mode
